In Japan...people did not scramble because nothing in their imagination had ever conceived of two single bombs that would kill hundreds of thousands in two blasts. It was a clear indication that the end was nigh.

Fast forward...Now such bombs are 30 and 40 times that strength. Putin has miscalculated the fight in Ukraine. He's gotten stuck but not likely for good. He has proven his conventional army and generals to be inept.

Last time I read a count the US has 60 nuclear submarines and 6000 warheads. I bet a bunch are in the area. Then there are the interballistics. If Putin goes nuke, Moscow will be vaporized within one hour. or less. It will literally be particles and debris. If he goes all out nuke there could be some headed our way that will reach their targets or close enough for nuclear horsehoes, the earth's atmosphere will be poisoned for many years, and civilization will (likely) be set back centuries. Chernobyl would look like a camp fire.

Putin is backed into a corner but he is calculating and not irrational.
Sorry to disappoint Tony, but I doubt Armageddon is here yet.

My "GUESS"...
Zelensky is going to have to be realistic and give up some land. The people of the world do not want to see it destroyed because of a comedian/ leader who refused to blink. (In the most corrupt country in Europe.)

But this guy Hal is making some hay while the sun is favorable to it.
